Under IPM, actions are taken based on monitoring results and necessity, rather than routine spraying.

• A. Monitoring results and necessity
• B. Routine calendar spraying
• C. Immediate, broad-spectrum pesticide use
• D. Ignoring pest presence

Answer: (A)

Under IPM, actions are guided by what monitoring shows and whether those conditions justify control. Pest monitoring—scouting, traps, and sampling—helps determine pest density and whether it has reached a level where intervention is warranted. When the monitoring indicates pest pressure above an action threshold, a targeted, appropriate control is chosen; if below threshold, no pesticide is used. This approach minimizes unnecessary sprays, protects beneficial insects, reduces resistance risk, and lowers environmental impact. Relying on routine calendar spraying ignores actual pest pressure and often leads to wasted effort and negative side effects. Using pesticides immediately and broadly without considering thresholds conflicts with IPM principles. Ignoring pest presence is the opposite of IPM, which relies on monitoring to decide when action is needed.
